The following examples illustrate a few embodiments of the invention.
EXAMPLES EXAMPLE 1 Synthesis of Benzoyl formic acid 3-iodo-prop-2-ynyl ester
(Compound #1)
To a cold, stirred solution of benzoyl formic acid (1.5 g, 0.01 mole) in methylene chloride (75 mL) at 4° C. were added iodopropargyl alcohol (1.9 g, 0.0105 mole) followed by 4-dimethylaminopyridine (0.122 g, 0.001 mole) and ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (2 g, 0.0104 mole). After stirring at 0° to 10° C. for one hour, the reaction mixture was diluted with methylene chloride (100 mL) and was washed with water (3×50 mL) and brine. The organic layer was dried over sodium sulfate, filtered, and concentrated to a residue. The residue was triturated with hexane and the product, a pale yellow solid, was collected by suction-filtration yielding 1.75 g (60%), mp=48°-50° C. An nmr spectrum showed the desired compound.
EXAMPLE 2 Synthesis of Ethyl 3-iodo-prop-2-ynyl oxalate
(Compound #5)
To an ice cold, stirred solution of iodopropargyl alcohol (2 g, 0.012 mole) in methylene chloride (50 mL) was added triethylamine (1.23 g, 0.012 mole). To the above solution was added dropwise over a 10 min period a solution of ethyl oxalyl chloride (1.65 g, 0.012 mole) in methylene chloride (20 mL). When the addition is complete, the mixture was allowed to stir at 0° to 5° C. for 10 min, then at room temperature for one hour. Thin layer chromatography (TLC) (EtOAc:Hexane=1:3) showed the reaction was completed. The reaction mixture was diluted with 50 mL of methylene chloride and washed with water (2×50 mL) and brine. The organic layer was dried over MgSO4, filtratered, and evaporated to give a residue. The residue was slurried with hexane and the solid was collected by suction-filtration affording 2.2 g (64.7%) as a white solid. mp=63°-65° C. An nmr spectrum showed the desired compound.
EXAMPLE 3 Synthesis of 4,6-Dimethyl-pyrimidin-2-yl oxalamic acid 3-iodo-prop-2-ynyl ester
(Compound #11)
To an ice-cold, stirred solution of oxalyl chloride (1.27 g, 0.01 mole) in THF (30 mL) under nitrogen was added, in one portion, a solution of iodopropargyl alcohol (1.81 g, 0.01 mole) in THF (10 mL). After stirring for 30 min at 0° to 5 ° C., a solution of 2-amino-4,6-dimethyl-pyrimidine (1.11 g, 0.009 mole) and triethylamine (2 g, 0.02 mole) in THF (30 mL) was added dropwise over a 10 min period. After the addition was complete, the reaction mixture (a white suspension) was stirred at room temperature for 40 min. The reaction mixture was then poured into ice cold water (250 mL) and the precipitate was collected by suction-filtration, washed with water, and dried in air. A recrystallization of the above crude product with methylene chloride/hexane yielded 2.1 g (58.7%) of pure product, mp=145°-150° C. An nmr spectrum (DMSO-d6) showed the desired compound.
EXAMPLE 4 Synthesis of 3-Methyl-phenyl oxalamic acid 3-iodo-prop-2-ynyl ester
(Compound #9)
To an ice-cold, stirred solution of oxalyl chloride (2.54 g, 0.02 mole) in THF (30 mL) under nitrogen was added a solution of iodopropargyl alcohol (3.62 g, 0.02 mole) in THF (10 mL). After stirring for 50 min at 0° to 5° C., a solution of m-toluidine (1.93 g, 0.018 mole) and triethylamine (4 g, 0.04 mole) in THF (30 mL) was added dropwise over a 20 min period. Following the addition, the reaction mixture (a white suspension) was stirred at room temperature for 2 hr. and then poured into ice cold water (500 mL). The precipitate was collected by suction-filtration, washed with water, and was dried in air to give 6.5 g of a pale green solid. A recrystallization of the above crude product with methylene chloride/hexane yielded 3.7 g (54%) of 3-methylphenyl oxalamic acid 3-iodo-prop-2-ynyl ester as a pure product, mp=170°-172° C. An nmr spectrum (DMSO-d6) showed the desired compound.
EXAMPLE 5 Biological Activity
Biocidal (bactericidal and fungicidal) evaluations were carried out.
A minimum inhibitory concentration (MIC) value is obtained using a broth, two-fold serial dilution test performed as follows: A stock solution or dispersion of the test compound, typically at a concentration of 1%, is made in a 5:3:2 solvent solution of acetone, methanol, and water. A volume of the stock solution is dispensed into culture media to give an initial starting test concentration of 500 ppm compound.
When the test is ready to be done, each vessel in the dilution series, except the first vessel, contains an equal volume of compound free broth. The first vessel contains twice the volume of broth with the starting concentration of test compound. One half of the broth from the first vessel is transferred to the second vessel. After being mixed, one half the resulting volume is removed from the second vessel and transferred to the third vessel. The entire cycle is repeated sufficiently to give a series of concentrations amounting to 500, 250, 125, 63, 31, 16, 8, and 4, 2, 1, 0.5, 0.25 ppm respectively.
Each vessel is then inoculated with a cell suspension of the appropriate test organism. Bacteria are grown in broth, fungi on agar slants for a time and at a temperature appropriate to the species being tested, and algae are a mixture of green algae and blue-green bacteria grown in a nutrient media. At the end of the growth period, in the case of bacteria, the broth is vortexed to disperse the cells.
In the case of fungi, the spores are harvested by pipetting water onto the slant and dislodging the spores with a sterile loop. The cell/spore suspension is standardized by controlling incubation time, temperature, and the volume of the diluent. The suspension is then used to inoculate the vessels containing the broth compound.
The vessels are then incubated at the appropriate temperature. After the incubation, the vessels are examined for growth/no growth. The minimum inhibitory concentration (MIC) is defined as the lowest concentration of compound that results in complete inhibition of growth of the test organism.
The organisms tested to demonstrate biocidal activity are shown in the Table 2:

EXAMPLE 6 Agricultural Fungicidal Activity
Compounds of the invention were tested in a fungicide in vitro screen. This screen is designed to provide information regarding the activity and spectrum of pathogen sensitivity on compounds. The compounds were tested against the following 8 organisms.
RHI Rhizoctonia solani
PYT Pythium ultimum
COL Colletotrichum lagenarium
HEL Helminthosporium sativum
PHY Phytophthora capsici
BOT Botrytis cinerea
PYR Pyricularia oryzae
SEP Septoria nodorum
The test employs an automated (Zymark Robot) microtiter bioassay system. Growth is measured spectrophotometrically with a Biotek microtiter plate reader, and corrected for absorbance due to the compound. The test will detect compounds which inhibit spore germination and/or mycelial growth.
Rhizoctonia and Pythium are tested as a dilute, uniform mycelial suspension. The remaining organisms are tested as a spore suspension in a yeast extract--glucose broth. Compounds are tested at 12 rates in a dilution series. Concentrations are: 50, 25, 12.5, 6, 3, 1.5, 0.75, 0.4, 0.2, 0.1, 0.05, and 0.025 ppm.
This test is designed to measure the MIC's of the compounds for each pathogen. The MIC's are determined from absorbance readings, as described above. An "F" before the MIC value indicates the compound exhibited a fungitoxic effect to that value. An MIC value of 6 ppm or less is considered active. The MIC's for the compounds tested are reported in Table 4.
